An electric train uses electric motors.
Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
Traction motors are used in electrically powered rail vehicles such as electric multiple units and electric locomotives, other electric vehicles such as electric milk floats, elevators, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems such as diesel-electric, electric hybrid vehicles and battery electric vehicles. Additionally, electric motors in other products (such as the main motor in a washing machine) are described as traction motors.
becoz of high starting torqe to move train
The DC motor acts as a generator. The electricity generated can be used to power the overhead (or third rail) line and used by other trains going up a hill, thus acting as a brake slowing the train going downhill.
it is a motopr which is used to drive the electrical vehicles
A relay cannot be used to power a motor. It can be used to control the motor by wiring the motor circuit in series with the relay contacts.
A traction motor is a type of electric motor used to power the driving wheels of a vehicle such as a railroad locomotive, electrical multi-unit train (such as a subway or light rail vehicle train), a tram, or an automobile. In other words there is a motor directly powering each wheel.A normal electric motor would have one motor powering many wheels through a driveshaft or some system to tranfer the energy.Traction motors are more efficient. They are more complex though, so DIY are going to stick with the simpler to build model with one motor
dc series motor is used for traction...
traction means propulsion of vichel and traction motor means the motor which propel the our object and it have tractive effort thats why we are saying traction and it is used in railways
dc series motors are used because of torque vs speed characteristics.

DC Traction Motor.
In delhi metro used motor is INDUCTION MOTOR.

It is economical and universal.
